Hubbell HGRKTD60DF Indoor Interlock Armored Tight Buffer Fiber Cable

Overview

The Hubbell HGRKTD60DF is a 6-fiber, OS2 single-mode, plenum-rated indoor fiber optic cable designed for robust data transmission in commercial and enterprise environments. Its interlock armored construction provides crush resistance and protection against physical damage, making it suitable for installations where the cable may be subjected to incidental contact or moderate stress. The yellow jacket signifies its plenum rating, indicating compliance with strict fire safety standards for air-handling spaces.

Compatibility

This cable is designed for use with standard fiber optic termination hardware, connectors (LC, SC, ST, etc.), and splicing equipment compatible with OS2 single-mode fiber. It integrates seamlessly into structured cabling systems supporting high-bandwidth applications such as IP surveillance networks, data centers, and telecommunications infrastructure. Ensure your termination and splicing equipment is rated for 6-fiber, OS2 applications.

Installation Notes

The interlock armor offers enhanced crush resistance, but care should still be taken to avoid sharp bends that exceed the minimum bend radius (typically 20x the cable diameter for OS2). The plenum rating means it can be installed in air-handling spaces, but local building codes and installation practices for plenum-rated cables must be followed. Termination requires standard fiber optic tools and connectorization procedures for single-mode fiber.
